will twitter revoke my app and access keys if i remove my phone number?

Question

I started using Twitter's API to get access to information from the users tweets and all the available resources, but i needed to verify with a phone number first. So I have verified my account on twitter with my phone number, so that i could get access token..etc

My question is: I have tried removing my phone number, and the access tokens and the app were still verified with no issues. My question is will the absesnce a phone number cause an issues for the generated access tokens ? or will it still work with no issues ?

Thank you.
